What is a CRYPT12 file?
A CRYPT12 file is an encrypted database created by WhatsApp Messenger, an Android messenger application. It contains a 256-bit AES encrypted database of messages sent and received through the app.
The "crypt12" extension is often appended to a .DB file to create a .DB.CRYPT12 file, which is used by WhatsApp to secure a user's message database on his or her Android device. For each new installment, WhatsApp Messenger uses a different algorithm to encrypt the DB files. The extension appended to the DB file, such as .CRYPT7 or .CRYPT8, signifies the algorithm.
If you are looking to decrypt a CRYPT12 to view the message history of the app's user you must locate the key file, which stores the encryption key. The key file is stored in the following location: /data/data/com.whatsapp/files/key
A CRYPT12 database file is located on the SD card of an Android device with WhatsApp Messenger installed. You can find it in the following directory:
